Project-specific drawings
Every Canadian solar project carries its own requirements. Roof layout, module placement, inverter selection, local permit rules and utility conditions all shape the documents you need. Therefore, accurate solar PV design and drafting help your crew coordinate these details before installation begins.
Our work supports contractors who need organized, project-specific drawings. In addition, we prepare solar permit plan sets, electrical drawings and single-line diagrams, depending on the scope you agree with us. You can read more about how we work across borders in our guide to a solar design partner for the UK, USA and Canada.

Canada-wide coverage
Solar Drafting Services in Canada, Province by Province
Canada does not run one solar permitting system. Instead, each province sets its own electrical rules, utility programs and climate conditions. Below, we explain how our solar drafting services in Canada adapt to each region. Please confirm current rules with the relevant authority, because programs and code editions change.

What Our Solar Drafting Services in Canada Include
Residential solar projects need more than panel selection. Contractors must coordinate system components, electrical connections, equipment data and submission paperwork. Consequently, PTOEdge prepares technical documents from the information you supply for each project.
Our goal is simple. We help solar professionals organize the details they need for permitting, engineering review where applicable, and utility interconnection submissions. Furthermore, our solar PV design & drafting services in Canada keep drawings, equipment data and electrical details consistent across the whole package.
Solar Layouts and Site Plans
A solar layout shows the proposed arrangement of modules and related equipment. Depending on the scope, our drawings identify roof areas used for the array, equipment locations and module configuration.
Electrical Drawings and Single-Line Diagrams
A single-line diagram (SLD) is a simplified electrical drawing. It shows how the array, inverter, distribution equipment and other components connect. It often identifies disconnects, protective devices and the connection point with the existing electrical system.
Final Requirements, Confirmed Early
The final drawing requirements depend on the project, the building rules and the reviewing authority. For that reason, we confirm these points at the start of each job.
Why the SLD must be consistent
A clear SLD helps reviewers and utilities understand the system quickly. Likewise, it must match the equipment specifications and every other electrical drawing in the package.
Point of common coupling (PCC)
For grid-connected projects, the point of common coupling (PCC) matters too. It marks where the customer’s system meets the wider electricity network. As a result, we show this point in the documentation when the utility requires it.
One coordinated package
Solar Permit Plan Sets for Canadian Projects
A solar permit plan set is a collection of drawings and technical documents that support a permit application. However, the exact documents depend on the municipality, the project and the authority reviewing the file. You can compare typical submission needs in our article on solar plan sets in Canada.
What a Canadian Solar Permit Plan Set Contains
- A site plan showing the property and building locations
- A roof plan with the proposed array layout
- Module and inverter specifications
- Electrical drawings and connection details
- A single-line diagram
- Relevant electrical and system notes
- Supporting structural information, where required and within the agreed scope
Not every project needs the same set. Therefore, you should confirm the current submission checklist with the relevant authority before you finalize the package.

Canadian Electrical Code and Provincial Requirements
The Canadian Electrical Code (CEC), also called the CE Code, gives Canada a national framework for electrical installations. You can read a neutral overview on the Canadian Electrical Code Wikipedia page. Meanwhile, each province and territory adopts its own edition and may add amendments.
One country, different code editions
For example, British Columbia adopted the 2024 edition of the CE Code, Part I, as the BC Electrical Code effective March 4, 2025. Consequently, a drawing package that works in one province may need changes in another. Our team designs around the code edition and checklist that apply to your project location and date.
What solar electrical drawings may show
Solar electrical drawings may need to show conductors, overcurrent protection, disconnecting means, grounding and bonding. Additionally, the details vary with the system configuration. We prepare the documents from the specifications you provide.
Grid connection
Utility Interconnection and Net Metering Documents Across Canada
Connecting a solar system to the grid involves the local utility or distribution company. In Canada, terminology and responsibilities vary by province. Therefore, you should obtain the utility’s current technical requirements before you finalize the design package.
Interconnection submissions often include application forms, equipment data sheets, site plans, electrical drawings and a single-line diagram. Additionally, larger systems may require extra information. PTOEdge prepares the design documents that fall within your agreed scope. You can find related guidance in our overview of solar permit design for residential projects.
In Alberta, for example, micro-generation customers apply to their distribution company and meet the applicable requirements. However, PTOEdge provides documentation support only. The utility makes interconnection, metering and connection decisions.

P.Eng.-Stamped Solar Drawings and Engineering Review
Some solar projects require professional engineering review or authenticated drawings. Whether this applies depends on the scope, the jurisdiction and the reviewing authority. For example, structural questions or unusual roof conditions may call for an engineer.
A P.Eng. is a Professional Engineer licensed in the relevant Canadian jurisdiction. Where authentication is required, an appropriately licensed professional must review and authenticate the work. Moreover, a stamp is never a formality, because it represents professional responsibility.
We discuss engineering requirements during project scoping. Furthermore, we offer stamped drawings only where an appropriately licensed professional provides that service within the agreed scope.

Solar Permit Plan Revisions and Design Updates
Solar projects often change after the first drawings. Equipment may change, roofs may need layout adjustments, and reviewers may request more information. As a result, revisions keep your documents aligned with the current design.
Depending on the scope, a revision may update the module layout, equipment specifications, electrical drawings or SLD. To speed things up, send us the latest drawings, a clear list of changes and any reviewer comments. In addition, changes that affect engineering assumptions may need further assessment before we issue revised drawings.
